The summer I got my IROC my buddy, Ralph, got himself a Buick Grand Nationalx. One day we headed to the back roads with Dino's '78 TA 6.6, Vince's 71 Supercharged Big Block Camaro and us. The intention was to do some burn outs and take some pictures. Ralph and I were leading the way when we stopped at the end of a long straight stretch to discuss what it was we were going to do. I pulled up alongside Ralph's drivers side and put the window down. Not a word was exchanged. I looked at him, he looked at me, I looked back and before you know it both our feet were on the gas as if there was some sort of mental telepathy involved!!!!
The GN got the jump on me and got about a fender length ahead of me and that's pretty much where he stayed until we got about a quarter mile down the road when.................

As a current owner of a TTA and GN and past owner of an IROC, I have to admit I still miss my IROC.
Me too that's why I got 'nuther one to rehabilitate. I've been a Camaro fan since I was a kid. I was never attracted to the TA's even though they're so similar to a Camaro and the GN's just seemed "plain" to me (something my grandfather would drive ) even though they kicked a$$.
If it was an 87 GN, he beats you badly, if it was a GNX he destroys you.
Not really. There really wasn't any huge performance upgrades between the GNX and the 87 GN. Nothing that would change a beat from a normal beat to a massacre. 245hp vs. 276hp. (under rated but those were the factory specs I believe) 30 more hp. meh.
I will give my 86 iroc to anyone who wants to trade their buick gnx. and ill give them a crisp 100$ bill.

Yes really. Most GN's ran mid 14's with the very rare 13.9. The GNX is a mid to low 13 sec car all day. The HP wasn't as important as the suspension difference. If you have seen the two launch in person you would know what I mean. So yes the difference is huge.

I'm pretty sure my 5.7 TPI was factory 225 HP and 300 lbs heavier than the GNx.
Ralphie asked me if I wanted another go when I get my project on the road. Problem is he hasn't got it anymore and wants me to have a go with is Viper! Hmmmm? Lemme think about that for a minute.....

Really? The GNX was almost a second faster than a GN. There were many upgrades to the GNX over the GN.
Just like a TTA. That car was a second faster than a 5.7 TPI but only rated 5hp more.

Nope, he traded it last fall for the Viper. I've got a picture somewhere of the GNx, my IROC and my buddies Hurst Olds. Gotta track that down.
Too each their own.... I guess! VIPER = PUKE! I know this a 3rd gen. site.... But come on fellas >>>> IMOP <<< all GM cars are great! I had a 79' & 82' cutlass, would love to see the pics with the HURST OLDS!

A high 13 isn't that rare. I've saw plenty of stock gn's knocking out 13 second times. Being a half second faster isn't going to make that big of a visual difference in a street race. That's what I was saying.

Meh, the Black TTA prototype would hand them all their @sses. My buddy got to see the car in action over in e-town back in '88, after GM wrapped production of the '89 models, and it ran a best of 10.99....
Being a half second faster isn't going to make that big of a visual difference in a street race....
Too many variables to say that though, especially when it comes to launching. Here are two guys that I know running against each other last year, w/Tommy pulling him the entire length of the track, but w/John finishing extremely close in terms of ET. If it were a half a second difference, it would have been murder....
well yeah, if one leaves later then the other one with bracket racing, it will look like that. But if they leave at the same time...
He didn't leave earlier, he just had a better launch, as well as sixty foot. Look at the dial in on the board before they pull through, Tommy was dialed in at 11.34. while John had 11.50, and Tommy let off at the end which his why his ET was a lot higher. We were originally talking about a half of second, and every tenth is about a half of car length, and a half of second would be quite a pull, even on the street. A turbo would definitely make up for it though...
A G.N. motor sure would be a nice asset to my 82' Regal. I'm just happy to have my Regal though in the condition she's in. V6 (3.8NA) Pokey but runs really smooth......
